Dark Social: We Have the Whole History of the Web Wrong

Just look at that graph. On the one hand, you have all the social networks that you know. They’re about 43.5 percent of our social traffic. On the other, you have this previously unmeasured darknet that’s delivering 56.5 percent of people to individual stories. This is not a niche phenomenon! It’s more than 2.5x Facebook’s impact on the site.
Day after day, this continues to be true, though the individual numbers vary a lot, say, during a Reddit spike or if one of our stories gets sent out on a very big email list or what have you. Day after day, though, dark social is nearly always our top referral source.
